It's called motivated reasoning. "Firefox must suck because I don't want to switch to it", so when firefox buys a bookmarking tool and integrates it into the browser, that's apparently "user hostile", while google wants to force your browser to attest that you haven't blocked any ads.
How can people complain about FF so much, when it's the only mobile browser that even gives you this option, and radically cleans up mobile browsing.
